INSECTICIDE AND PROCESS OEPREPARING SAME.

No Drawing.

To all whom it may concern Be it known that I, LOUIS TERRY, a citi-- zenof the United States, residing at Pine Bluff, in the county of Jeffersonand State of Arkansas, have invented certain new and useful Improvementsin Insecticides and Processes of Preparing Same, of which the followingis a full, clear, and exact specification.

This invention relates to a composition of matter designed and adaptedto kill insects of various kinds, and to the method of preparing suchinsecticide. This composition is especially designed as a means ofexterminating the boll weevil which menaces the cotton crop, but is alsouseful in destroying other insect pests, such as attack fruits, trees,plants, vines and vegetables.

The object of. the invention is to produce a composition which willpositively kill these insects in the egg as well as in the full growthand which may be easily and inexpensively prepared and applied.

In preparing the insecticide, the following ingredients are used in theproportions specified: 12 pounds of tobacco, of any preferred brand; 2pounds of soda, of any preferred brand, 65 gallons of water. It will beunderstood that this formula is given as an example and that larger orsmaller quantities of the compound may be prepared by varying theamounts of the different ingredients as long as their proportions aremaintained.

The tobacco and soda are put into the water and boiled for approximatelyone hour and a half, care being taken to stir it well while boiling. Thetobacco is then pressed to extract the essence thereof which it containsafter the boiling. The resulting liquid compound will measureapproximately sixty gallons, five gallons being lost during the boilingperiod.

For killing the egg or the adult of the boll weevil in the cotton seedbefore planting, the seed is first mixed with dry earth, preferablylight loam, and the liquid compound prepared in accordance with myinvention is then poured over this mixture and the whole rubbed welltogether. An ordinary hoe may be used to advantage in effectingthismixing and rubbing which is continued until the mixture is in a semi-Specification of Letters Patent.

solid or plastic state and has a muddy appearance. This mixture is leftin a stack or heap for a day and a night, during which the seeds gothrough a sweating process whlch causes them to swell soon afterplanting. The next day the seeds should be planted and in no instanceshould they be kept more than two days after going through this sweatingprocess because my preparation causes them to sprout almost immediately.During this process of treating the seed with my compound the egg andadult of the boll weevil are absolutely killed as well as all otherinsect life whichmight have a harmful effect upon the seed or plant.

If when the cotton plant is growing boll weevil are found in any state,they may be eXterm-inated by using my liquid compound as a spray. Thisspray will also kill any other worm or insect found on the plant,including the bug known as the sharpshooter which is as much feared insome localities as the boll weevil. Actual tests have shown that insectsof the kinds referred to will be killed in thirteen seconds after beingstruck by my compound.

Used as a spray, my compound is also eflicacious for killing all kindsof insects, bugs, and worms that infest fruit trees and vines,vegetables and flowering plants and bushes. In applying the remedy torose bushes care should be taken to thoroughly spray the stalk as wellas the leaves and buds.

Although the compound is sure death to all destructive insects, it isabsolute y harm less to the cotton boll, to fruits, vegetables orflowers, and also to man or beast.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. The process of preparing a liquid insecticide which consists incombining tobacco, soda and water, in substantially the proportionsspecified, i. 6., twelve pounds of tobacco, two pounds of soda andsixty-five gallons of water, boiling the mixture until the liquidtherein is reduced approximately eight per cent, and expressing theliquid from the resulting mass.

2. A liquid insecticide resulting from the boiling of tobacco, soda andwater, in substantially the proportions specified, i. e.,, name to thisspecification in the presence of twelve pounds of tobacco, two pounds oftWo attestlng Witnesses. soda and sixty-five gallons of water, until theliquid in the mixture is reduced ap- LOUIS TERRY 5 proximately eight percent., substantially as Witnesses:
